Abstract/OtherAbstract:
PURPOSE: This study was designed to assess the long-term outcome of selected patients with aortic, aortoiliac, and isolated common iliac aneurysms treated with the GORE EXCLUDER(®) stent-graft. METHODS: Between December 1998 and June 2010, 121 nonconsecutive patients underwent insertion of a GORE EXCLUDER(®) stent-graft to treat an aortic (n = 80; 66%), aortoiliac (n = 25; 21%), or isolated common iliac (n = 16; 13%) aneurysm. Procedural and follow-up data were collected prospectively. Primary endpoints are overall survival, intervention-free survival, and freedom from aneurysm rupture. Secondary endpoints are device- and procedure-related complications, including all types of endoleaks or endotension, and reintervention. RESULTS: The mean follow-up is 4.98 years (standard deviation, 3.18; median follow-up, 4.05 years). The estimated percentage overall survival (with 95% confidence interval) after respectively 5 and 10 years of follow-up is 74.5% (65.8; 81.3) and 57.8% (47.7; 66.7). The estimated intervention-free survival after respectively 5 and 10 years is 90% (84.3; 96.1) and 77.7% (67; 88.4). There was no aneurysm rupture during follow-up. Early postoperative complications occurred in 16 patients (13%); none were fatal. Late reinterventions were performed in 18 patients (15%). Finally, throughout the follow-up period, endoleaks were identified: type I (n = 4; 3%); type II (n = 39; 32%); type III (n = 0; 0%); endotension was seen in 11 patients (9%). CONCLUSIONS: Aneurysm exclusion with use of the GORE EXCLUDER(®) stent-graft is durable through a mean follow-up of nearly 5 years. There was no postprocedural aneurysm rupture. Complications occurred throughout the follow-up period, requiring continued clinical and radiological surveillance.
